  • Controller, dynamic differential pressure transducer and actuator in one casing
  • Use in ventilation and air conditioning systems, only with clean air
  • Simple plug connection RJ12 for supply voltage and communication
  • Compatible with X-AIRCONTROL zone module Modbus
  • Volume flow rates qvmin and qvmax are pre-set in the factory and saved in the controller as changed parameters

  • Setpoint value settings, override controls, parameter adjustment via bus communication or X-AIRCONTROL
  • Service access for manual adjustment devices and PC configuration software

 


General information

Application

  • All-in-one control engineering devices for VAV terminal units
  • Dynamic differential pressure transducer, electronic controller, and actuator are fitted together in one casing
  • Suitable for different control tasks depending on the specification of the setpoint value
  • The room temperature controller, central BMS, air quality controller or similar units control the variable volume flow control by specifying the setpoint values via a communication interface.
  • Suitable for room control X-AIRCONTROL zone module Modbus
  • Simple connection for supply voltage and communication with common RJ12 connection socket
  • Override controls for activating qvmin, qvmax, shut-off, OPEN position via Modbus register, BACnet objects or X-AIRCONTROL possible
  • Volume flow rate actual value is available as a network data point
  • Damper blade position is available as a network data point
  • Standard filtration in comfort air conditioning systems allows for use of the controller in the supply air without additional dust protection

 


With heavy dust levels in the room

  • Install appropriate exhaust air filters upstream, as a partial volume flow is routed through the transducer for volume flow rate measurement

 


If the air is contaminated with dust, fluff or sticky components

  • Use an attachment assembly with static differential pressure transducer



Control strategy

  • The volume flow controller works independently of the duct pressure
  • Differential pressure fluctuations do not result in permanent volume flow rate changes
  • To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move
  • Flow rate range parameterised in the controller at the factory (qvmin: minimum volume flow rate, qvmax: maximum volume flow rate)
  • Operating parameters are specified via the order code and parameterised in the factory




Operating modes

  • Modbus RTU: Setpoint value setting via X-AIRCONTROL or external software
  • BACnet MS/TP: Setpoint value setting via external software

① Effective pressure transducer

② Actuator

③ Volume flow controller

④ Setpoint value signal

 

A closed control circuit for regulation of the volume flow rate, i.e. measuring - comparing - adjusting, is characteristic of air terminal units.
The volume flow rate is measured by measuring a differential pressure (effective pressure). This is done via a differential pressure sensor. An integrated differential pressure transducer converts the effective pressure into a voltage signal. The volume flow rate actual value is hence available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal volume flow rate (qvnom).
The volume flow rate setpoint value is specified by a higher-level controller (e.g. room temperature controller, air quality controller, central BMS). Variable volume flow control results in a value between qvmin and qvmax. It is possible to override the room temperature control, e.g. by a complete shut-off of the duct.
The controller compares the volume flow rate setpoint value to the actual value and controls the integral actuator accordingly.


Category

  • Compact controller for volume flow rate
  • Regulation of a constant or variable volume flow rate setpoint value
  • Electronic controller for connecting a controlled variable and tapping an actual value for integration in a Modbus RTU or BACnet MS/TP-based central building management system
